Thanks for your reply Webstar22.
I'm aware of those links,however what I'm really looking for is a master frequency list in a numerical sequence that includes trunking frequencies in Ontario.
Sorry if I wasn't clear enough in my query.

You won't find a useful "master list" by frequency alone as in this day
and age it's of limited usefulness. The old Haruteq lists and CDs had their
day, mostly pre-internet. Even the RR Database CDs will have a limited
lifetime given the speed a which some things change.

Beware of old frequency lists (other than here) hanging around out
there. Some were not that great ever when they were current, which
in some cases was literally decades ago. It's funny to see old users
who have not been around for years, or have migrated through one or
more new systems.

Even without an RR Premium Subscription you can look up (but
not download to a scanner) trunked systems by location and user name,
including Ontario. You can search for a system by system ID (if known);
or frequency and system type e.g. EDACS, which returns all systems
which match. Signing up to RR ($) gives more search/download
capability.

IC search (TAFL) can yield a lot of info, but it has limitations and
you need to know how to use it; not just access the information, but
interpretation. Much sensitive gov't/military/police and even some
less-sensitive info is "blocked" (for our own good, of course...).
Also, system info such as talkgroups isn't held by IC, it's a provider
thing and basically what's on this database was gathered by listeners
(or from radio "codeplugs" but that's a whole different topic).
Further to that, old systems show up which are no longer in use, or have
changed, still listed if the licence is still valid, which can be
confusing. Still, the IC database has given me lots of valuable data
including "pending" assignments which are not necessarily on the
air yet.

That one isn't the real IC database, but a copy that's downloaded periodically
and may or may not be up to date. The "real" TAFL search is a bit more work to
set up but can yield a whole lot more detailed info (such as whether a frequency
is digital or analog). I use the darkwing search occasionally, but it's a limited
subset.

I wanted to know how up to date the NEON TAFL list was...Id very , when my frequency was Published , it was also on NEON right away,! Id say it is very fast to update...might be a cgi script to read and format tafl's list...My Radio guy at IC , he uses NEON as well...says its fast when he works at home..I should ask what he thinks of the updates or is Neon a script that reads the tafl list...Hmm

The server that it used to run on suddenly went down in early September and I've moved it all over to my own domain. Please update your bookmarks: http://tafl.mckie.ca

We're still working through some small glitches leading to the occasional 404 error message when you try to run a search, but I hope to have that fixed shortly.

As to how up-to-date it is, I can tell you that IC updates their downloadable files on the first workday of each month (sometimes the second day, but they are good about it) and as soon as I see that has happened, I will update the data at http://tafl.mckie.ca. The date of the last update is always posted on the main page of the site, under "Latest News"

I saw the comment that it is a limited subset of the data, and that's absolutely true. I'm going to use the opportunity of moving to a new server to try to add in some more fields of data and possibly new features like the Google Map integration (with full credit to jonathanmorgan.net, that was a great idea!).

What would you like to see added?

Thanks Alasdair. I use your search occasionally, and find it useful, especially in
cases where IC/SD is down.

For starts, I'd suggest if you could add:

Callsign: getting callsign and doing further search allows to you find all other frequencies
related to that licence.

TX ERP: not just TX power, includes losses and gains. This gives some idea how far you
can normally hear the system. TAFL gives it in dBW, so you might be good to convert
to straight W (I'm used to dBW, but not everybody is). Of course, range is also
affected by antenna elevation, surrounding terrain etc.

Class of Emission: gives a good idea (in conjunction with Necessary Bandwidth).
what type of signal to expect. I am able to distinguish normal analog voice from NFM,
P25, NXDN, TRBO etc. Of course, these are coded, so people would need to get used to
decoding, but TAFL lists these, and it's really not too big a challenge.

Thanks for the input - I'll definitely look at adding that data. First I have to figure out how to keep the interface light-weight for those who still appreciate its simplicity while expanding the available information.

Well, actually first I have to figure out why it keeps giving 404 errors for no apparent reason. One thing at a time.
